(17:9) Indeed, this Qur`an guides to that which is most suitable and gives good tidings to the believers who do righteous deeds that they will have a great reward. (17:10) And that those who do not believe in the Hereafter - We have prepared for them a painful punishment. (17:11) And man supplicates for evil as he supplicates for good, and man is ever hasty. (17:12) And We have made the night and day two signs, and We erased the sign of the night and made the sign of the day visible that you may seek bounty from your Lord and may know the number of years and the account [of time]. And everything We have set out in detail.
